Former President Barack Obama surprised Michelle Obama with a video tribute on Tuesday to celebrate the couple’s 25th wedding anniversary.

The former first lady was wrapping up a question-and-answer session at the Pennsylvania Conference for Women when moderator Shonda Rhimes revealed an unexpected surprise.

“It’s been a very special day for all of us, but I also know it’s a very special day for you. And so I have a little bit of a surprise. Can you roll the video?”

A video of the former president then began playing as Michelle broke into a wide smile.

“I had to crash this party because today we have been married for 25 years,” President Obama said in the video, prompting loud cheers from the audience.

“Not only have you been an extraordinary partner, not only have you been a great friend, somebody who could always make me laugh, somebody who would always make sure that I was following what I thought was right, but you have also been an example to our daughters and to the entire country,” he said.

He continued: “Your strength, your grace, your determination, your honesty, the fact that you look so good doing all this, the way in which you’ve always taken responsibility for your own actions but also for looking out for the people around you, is remarkable. And it’s no wonder that as people got to know you the way I got to know you that they fell in love.”

He said asking Michelle on a date was “truly the best decision that I ever made.”

“I figured that you wouldn’t mind maybe me parachuting in just to say how much I love you,” he said.
